On Wednesday, the "Scream and Shout" singer tweeted her support for "We Can't Stop," writing, "#wecantstop blasting @mileycyrus new song! So hot!"

Miley also seems to be a fan of her fellow erstwhile Disney star. In her 2009 hit "Party in the USA," her lyrics said her "tummy's turnin'" and she's "feelin' kinda homesick," right up until "the Britney song was on!" And, then you know, she put her hands up, they're playin' her song, the whole shebang.
